    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 RpOGY{[)[  
    1~zzQ:jAZ  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: '-N `u$3Y  
    enableservice('AutomationServer', true) w/IYQC\v  
    enableservice('AutomationServer') g=XvqD<  
    LPc)-t|p"  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 anxg D?<+B

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:  iVu  
    1. 在FRED脚本编辑界面找到参考. - 0R5g3^*/  
    2. 找到Matlab Automation Server Type Library (y *7 g f  
    3. 将名字改为MLAPP K`{P/w

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 `*g(_EZsS

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c @7d4Jz  
    1. 创建Matlab服务器。 NvW`x   
    2. 移动探测面对于前一聚焦面的位置。 _2xNio&  
    3. 在探测面追迹光线 Z$LWZg  
    4. 在探测面计算照度 B52n'.  
    5. 使用PutWorkspaceData发送照度数据到Matlab }Go?j# !  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #.L9/b(  
    7. 用Matlab画出照度数据 RtO3!dGT.
